Mixt.re models have b.come more popular in modelling compared t. st.ndard dist.ib.t.ons. t.e mixing dist.ib.t.ons play a role in capt.ring t.e variab.lit. of t.e random variab.e in t.e condit.onal dist.ib.t.on. St.dies have lat.ly focused on finit. mixt.re models as mixing dist.ib.t.ons in t.e mixing mechanism. In t.e present.work, we consider a Normal Variance Mean mixture model. The mixing distribution is a finite mixture of two special cases of Generalised Inverse Gaussian distribution with indexes -1/2 and -3/2. t.e parameters of the mixed model are obtained via the Expectation-Maximization (EM) algorit.m. t.e it.rat.ve scheme is b.sed on a present.t.on of t.e normal equat.ons. An applicat.on t. some financial dat. has b.en done.

采用摇瓶和玻璃柱试验考察了Fent.n氧化处理爆炸物污染土壤中2,4-DNt.2,6-DNt.及COD等的去除效果及其最佳参数.当3%H2O2投加量达到26.46mmol、FeSO4和H2O2的物质的量之比约为1:73.56时,2,4-DNt.2,6-DNt.可被完全氧化,COD去除率可达到87%.对于2,4-DNt.2,6-DNt.反应时间只需要2h,但要同时去除其它芳香族硝基化合物,则反应时间需要超过8h.土壤直接Fent.n氧化的效果并不理想,而对洗出液进行Fent.n氧化可以取得很好的效果.通过反应动力学分析和丙酮抑制试验得出,2,4-DNt.2,6-DNt.易氧化.GC-MS分析结果表明,不仅土壤中的2,4-DNt.2,6-DNt.被氧化,其它的硝基芳香族有机化合物也可被氧化去除.
